Sedum plant named &#39;dynomite&#39;

ABSTRACT

A new and distinct hybrid of  Sedum  plant substantially as shown and described, characterized by burgundy red flowers in good size inflorescences, leaves with dark leaf margins and red tints, a very dwarf, clumping habit.

BOTANICAL DENOMINATION

Sedum hybrid (syn. Hylotelephium)

VARIETY DESIGNATION

‘Dynomite’

PARENTAGE

Sedum telephium 2-7×Sedum spectabile ‘Neon’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedumand given the cultivar name of ‘Dynomite’. Sedum is in the familyCrassulaceae. Sedum ‘Dynomite’ originated from a planned breedingprogram to produce hybrids with dark leaves, short stems and largeinflorescences. Sedum ‘Dynomite’ originated from a cross between anunnamed, proprietary, an unpatented Sedum telephium 2-7 as the seedparent and Sedum spectabile ‘Neon’, unpatented, as the pollen parent.

Compared to the seed parent Sedum telephium 2-7, the new cultivar is haslarger inflorescences with better flower color, and lighter coloredleaves.

Compared to the pollen parent, Sedum spectabile ‘Neon’, the newcultivar, has leaves that have a red leaf edges and red tint in full sunrather than yellow green.

Compared to Sedum ‘Birthday Party’, (U.S. Plant Pat. No. 22,826), thenew variety has a smaller and tighter habit and smaller inflorescences.

This new and unique Sedum is distinguished by:

1. burgundy red flowers in good size inflorescences,

2. leaves with dark leaf margins and red tints,

3. a very dwarf, clumping habit.

This new cultivar has been reproduced only by asexual propagation(division and tissue culture). Each of the progeny exhibits identicalcharacteristics to the original plant. Asexual propagation by divisionand tissue culture using standard micropropagation techniques withterminal and lateral shoots, as done in Canby, Oreg., shows that theforegoing characteristics and distinctions come true to form and areestablished and transmitted through succeeding propagations. The presentinvention has not been evaluated under all possible environmentalconditions. The phenotype may vary with variations in environmentwithout a change in the genotype of the plant.
